DZR Press Fittings (F5b)

Unique structure
1. Two O-rings placed on the fitting insert.
2. Three annual grooves on the three-step-labyrinth structure inset.
3. Perfect sealing performance.
High quality sealing material:
The material of Ardi F5 fitting O-ring is EPDM, which has excellent specialty of anti-aging, well-rebound and long lifetime performance. It ensures no leaking in the piping system for long term use.
Secure connecting way:
The safe and stabile connecting lies on the permanent compression plastic deformation on the stainless steel sleeve by using the special pressing tool to complete the connecting correctly.

Standard brass components have been accepted universally in water distribution. However, they can experience a severe form of corrosion known as dezincification when they are exposed to particular combinations of pH and concentrations of chlorides. In order to avoid such a problem, we replaced the raw materials (C37700 brass) of press fittings with dezincification resistant brass alloy (DZR brass), which contains a certain amount of inhibiting agent to minimize dezincification damage. F5b DZR brass press fittings are listed by NSF and IAPMO to be in compliant to the Uniform Plumbing Code. They are manufactured according to ASTM F1281-2005 standard and CSA137.10 standard.
